What is the the electric flux through the top face of the cube if the electric field in the region is E=(8i^+2j^)N/C where y is in m ? 72 N m2/C 12 N m2/C none of the other answers is correct 126 N m/C 54 N m2/C 18 N m2/C
For the RC circuit shown, R=10.0Ω,C=5.0 F and the battery has a voltage of 12 V. The capacitor is initially uncharged when the switch S is closed at t=0.0 s. At sometime later, the current in the circuit is 0.50 A. What is the magnitude of the voltage across the capacitor at that moment? 6.0 V ov none of the other answers is correct 7.0 V 5.0 V 12 V
The tungsten filament of a lightbulb radiates 2.00 W of light. The filament has a surface area of 0.300 mm2 and an emissivity of 0.950. Find the filament's temperature. (The melting point for tungsten is 3683 K and Stephan Boltzmann constant is σ=5.67×10−8 W⋅m−2⋅K−4 ) 3.34×103 K none of the other answers is correct 105 K 378 K
The electric potential in a region in space is given by V(x,y,z)=10x+20xy2−15z V. The the y-component (in N/C) of the electric field at a point P that has the coordinates (−1,−1,−2)m is: −40 V/m none of the other answers is correct 20 V/m −20 V/m 40 V/m
